11 Questions Lady Gaga & Adele's Selfie Left Me With — PHOTOS

Musical worlds are colliding, people! Late on Wednesday night, Lady Gaga and Adele took a selfie together and put it up on Instagram. Understandably, the Internet exploded. But just what were the two singers up to? The only real clue we have is Gaga's bizarre Instagram caption that reads: "Nothing like a Wednesday night bro-down with the beautiful Adele."

A Wednesday night bro-down? What the hell is that? A party? Is everybody going to bro-downs these days but me? Obviously, I don't know Gaga or Adele personally, but neither of them strike me as the kind of person who would be terribly interested in a bro-down. OK, now I'm even more confused.
